Geothermal Alliance of Illinois


Geothermal is the most efficient, environmentally-friendly and best heating and cooling technology available today. Don’t take our word for it. That assessment comes from the U.S. Environmental Protection Agency. Geothermal takes the earth’s free energy and moves it into your home or business. No gas, no combustion, no flame. Just comfort, with efficiency and economy. Need more information about geothermal? Want to know how to find a qualified contractor/installer? You’ve come to the right place. The Geothermal Alliance of Illinois (GAOI) is THE source for information about geothermal heating and cooling.
